Answer:

1. It is because of the enormous pressure. The gravity of the earth can pull you down and as you go deeper, the hotter you'll feel.

2. Geothermal energy is heat within the earth. The word geothermal comes from the Greek words geo (earth) and therme (heat).

3. Low-temperature geothermal energy is derived from geothermal fluid found in the ground at temperatures of 150ºC (300ºF) or less.

4. Geothermal heat pumps, which tap into heat close to the Earth's surface to heat water or provide heat for buildings.

5. Hot water is pumped from deep underground through a well under high pressure. When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam. The steam spins a turbine, which is connected to a generator that produces electricity.

6. Flash steam plants take high-pressure hot water from deep inside the earth and convert it to steam to drive generator turbines.
